An integral requirement of any educational program is the chance to evaluate the effectiveness of the delivery of education. Traditionally evaluative tools of various sorts have been used to measure the process and product of teaching. More recently however as far as English as a second/foreign language is concerned more innovative alternative assessment procedures have been practiced for decades. The problem however with all such assessment techniques has been that they have been static in nature in that they have been meant to measure the product rather than the process of education. Dynamic assessment, which views assessment as an integrated part of teaching rather than as its final loop, has accordingly been proposed as an alternative and complement to static or standardized types of assessment. The focus of this book is on the viability of using dynamic as an instructional adjunct in the development of EFL learners' grammar. The audience of the book includes assessment experts, ELT professionals and SLA researchers.
